Description
Experience the pure performance sound of the 6.2L LT2 engine with the CORSA 3.0" Cat-Back Exhaust System for the 2020–2024 Chevrolet Corvette C8. Designed exclusively for models equipped with Factory NPP (dual-mode exhaust), this system delivers both exhilarating tone and precision-engineered performance.
CORSA’s exclusive cast valve assemblies were fully redesigned to endure the extreme heat produced by the C8’s mid-engine layout. These precision valves integrate seamlessly with the factory actuator motors, maintaining all OEM driving sound modes without triggering a Check Engine Light (CEL).
The CORSA NPP Cat-Back enhances the Corvette’s exhaust tone by delivering up to +9 decibels louder in track mode and 1 decibel quieter in touring mode than the stock system. The result is a perfectly balanced experience — aggressive and thrilling under acceleration, yet refined and composed during cruising.
Constructed from premium T304 stainless steel, the 3.0-inch mandrel-bent tubing maximizes exhaust flow and reduces backpressure for improved performance and throttle response. The quad 4.5-inch Pro-Series dual wall slash-cut tips provide a race-inspired finish, available in multiple finishes including polished, black, and carbon fiber.
